Aren’t bachelorette parties supposed to be fun? The ladies of Bravo’s The Real Housewives of Orange County seemed to forget that little tidbit. Last week, Vicki Gunvalson decided to show Tamra Barney and Lydia McLaughlin how to get down in Puerto Vallarta by partying the night away. Too bad Vicki and the gals didn’t clue in Gretchen Rossi and Heather Dubrow, who were at the restaurant wondering where the girls were.

Vicki had enough of the prim and proper hen party weekend for Tamra, and spirited her former BFF and newest housewife Lydia away for a real South of the border experience. While the gals all cackled about contacting Gretchen and Heather, none of them took the time out to give them the heads up on what they were doing. With all the tension between Vicki and Gretchen, you would think this would be a peace offering of sorts. Instead, it became another incident for the two feuding divas to break out their jewel-encrusted claws.

As Vicki, Tamra and Lydia channeled their inner sorority girl, Gretchen and Heather fumed about being ditched and decided to split for the hotel. Gretchen also chose this opportunity to fill Heather in on the allegations Lauri Waring-Peterson lobbed at Vicki. Heather saw right through Gretchen’s antics, and let her know she didn’t give two hoots about what escapades Vicki participated in the past. She and her ex-Donn were divorced now, so why should it matter?

Bravo (no pun intended) for Heather! Look Gretchen, if you are disturbed about what you’ve learned about Vicki, considering she’s been riding you hard about your late fiancée Jeff, you’d try to confront her instead of pulling a Lauri and trash talk.

Later, Vicki, Tamra and Lydia finally dragged their drunk and disorderly selves back to the hotel, and faced the wrath of Heather and Gretchen. The women tried to apologize for their behavior, but both Heather and Gretchen weren’t in a forgiving mood. Come on girls, they left you in a restaurant to go bar hoping; they didn’t leave you in Guantanamo Bay! Lighten up already.

By the next day, all appeared to be forgiven. However, as the ladies took a trip to see the sights Puerto Vallarta had to offer, Lydia just had to bring up the previous night! Girl started going on and on about all the fun they had and how it made the trip, which set Heather and Gretchen off. Lydia let the two chicks know, she was sorry, but isn’t about to keep falling on bended knee for the error she made. Seriously ladies, if you were so hurt and wanted to go, why didn’t you call them to find out where they were? While Gretchen cried her tears about being hurt for the slight, it made you wonder if she was jealous Vicki was the one who showed Tamra a good time and not her. We all know the PV trip was her idea, and how shady was it that Vicki upstaged her at her own event? Guess Gretchen has to get up a bit earlier in the day to best Vicki. Nice move, Gunvalson.
